Other Parts Discussed in Thread: BQ25672
Using the BQ25672 EVM, I want to charge a 1 cell LiIon even during dim solar power conditions. I noticed the Charge Current Limit register 0x3h range is limited to 50-3000mA. Does the chip support charging/MPPT at lower currents e.g., 5 - 50mA? Do you have a graph of the battery charge efficiency at these lower charging currents with VBAT = 4V and PFM enabled?
